playbar wont connect or reset

Hi looking for some help with my playbar. All has been working fine for the whole time I’ve owned it, but this week I started to have problems. In my living room I have a playbar with two play1’s as surround speakers. They all stopped working and were not connecting to the app. The speakers in other rooms were not affected and continued to be useable. I managed to reset both the play1’s and add them back without a problem, but the playbar won’t reset or connect. The white light come on the playbar as soon as you plug it in, and then nothing else. I tried to contact the online help support, but they kept going around in circles saying hold the play/pause button when connecting power. I kept telling them I’ve done that 100 times and it won’t reset. I’ve looked at my router to see if it was connecting or has an ip address, but it was showing as not connected. I deleted it off the router incase it would sort out a ip problem and would connect again, but so far nothing. 
does anyone have any ideas what could be causing it? Or a way to fix it?
